3.9.1How to do post processing

The post processing functions CALCulate1 and CALCulate2 comply with the front panel functions MATH1 and MATH2 of the CombiScope instrument. They work only in the digital mode. The use of the CALCulate functions is as follows:

1Select the source for the post processing function.

2Specify the settings of the post processing function.

3Enable the post processing function.

4Check the result of the post processing function.

3.9.1.1Select the source for the post processing function.

Select the trace that is to be sourced into the CALCulate function by sending the CALCulate<n>:FEED command.

Examples:
Send → CALCulate2:FEED "CH3"	’Channel 3 = source for CALC2
Send → CALCulate:FEED "M2_1"	’M2_1 = source for CALC1

Empty traces may not be selected as input trace. A memory register 1 location (M1_ j) may not be specified as the source (feed) for CALCulate1 and a memory register 2 location (M2_ j) may not be the source (feed) for CALCulate2. After a *RST command, CH1 becomes the input trace for both CALculate functions.

Note: CH3 and CH4 cannot be selected as source for the PM33x0B CombiScope instruments.
